Description

In a simple model (FLRW or Bianchi I minisuperspace and Wheeler De Witt), I discuss how the singularity can be avoided by defining quantum trajectories. This permits to classify clocks and could thus be related to the issue of time. Applying similar procedures to perturbations, the primordial power spectrum can be affected, leading to possibly detectable consequences in the cosmic microwave background or large scale structure data.
